France opened a flurry of nuclear power plants in the 1980s and 1990s

At the turn of the millennium, France had one of the lowest-carbon electricity grids in Europe (and the world). While countries like the UK and Germany emitted well over 500 grams of CO₂ per kilowatt-hour of electricity, France emitted just 80 grams — six times less. This was mostly thanks to nuclear power.

In the 1980s and 1990s, France rapidly expanded its power grid, and almost all of this growth came from new nuclear plants. The chart shows this: in the 1980s alone, nuclear power grew from 60 to over 300 terawatt-hours.

By 2000, nuclear power supplied almost 80% of the country’s electricity, making it much cleaner than its neighbors, mostly relying on coal and gas.

France still has one of the cleanest grids in Europe, although it has added very little nuclear power in the 21st century. It has opened just one plant in the last 25 years, in Flamanville, following long delays and cost overruns.

In the last decade, solar and wind power have grown the most.
